IMPROVEMENT IN WATER-SPOUT CUT-OFFS.

' Specification forming part of Letters Patent No. 176,491, dated April 25, 1876; application iled August 31, 1875.

To all whom it may conc'era:

Be it known that I, EDWD. STEWART, of

Fort Madison, in Lee county, and State ot' `Iowa, have invented an Improved Water- Spout Cut Oft', (which invention is an improvement on my cutoff patented March 28, 1871, and numbered 113,108,) of which the following is a specification:

In the drawing accompanying' this specification, Figure l represents the cut-oft', partly in section, in position as when no rain is falling, and at the commencement of a rain. Fig. 2 shows the same device in the position automatically 'assumed after the roofs have become thoroughly washed by the rain.

The object ot' this invention is to produce a cut-ofi' which is entirely automatic in its action, instead of requiring to be reset after every rain.

I will now describe the invention by referring to the drawing, in which the same letters refer to like parts in both figures.

A is the casing or jacket of the apparatus, and is provided with an induetionpipe, B, and two eduction-pipes, C D, the one, G, leading to the cistern or reseryoir, and the one, D, to the surface of' the ground, or into a convenient drain or sewer. To the lower part of the induction-pipe B is suspended, on a pivot, a, the funnel-shaped extension E, so as to have a swinging motion on said pivot, from side to side, within the casing A. This funnel-shaped extension E is controlled, as to its. position within the casing A, by a weight or weights, G, in one direction, and by the accumulated water in the bucket H in the other direction,

so that when no rain is falling the weights G, operating through the elbow-lever I, by its pivot c at the upper end, on a groove or slot, d, formed on the side of the funnel E, retains said funnel in the position represented in Fig. l until the drip or leak from the chute e has lled the bucket H, during which time the roofs have become thoroughly washed olf. The water in the bucket, then overbalancing the weights G, operates through the lever I to throw the funnel to the position represented in Fig. 2, when the water passing through it will be conducted to and through the pipe C to the cistern or reservoir, while any waste there may be in the bucket H is replaced by the leak through the chute f in the then lower side of the funnel until the rain ceases, when, this supply also ceasing, the Water in the bucket H slowlyleaks out through an aperture, i, at or near its bottom, to allow the weight G to preponderate, and thereby to swing the funnel to its normal position, in readiness to repeat the same operation whenever another rain may occur. t

What is here claimed as new, and desired to be secured by Letters Patent, is

The arrangement of the leak-critices e and f in the opposite sides of the pendent funnelshaped chute E, in combination with the bucket H and weight G, as and for the purposes specilied.
